<p>The invention relates to a method and a light source device for supplying light to illuminate an object. A light array comprising LED units that are arranged adjacently to one another and emit light of different wavelength ranges is linearly shifted such that said LED units are selected one after another, each selected LED unit is switched on, the light emitted by each switched-on LED unit is focussed on a linearly shiftable filter, and said linearly shiftable filter is shifted such that, out of the light incident on the filter, it is light with a smaller wavelength range that passes through.</p> |
